    This paper attempts to quantitatively measure the change in the productivity of Danish organic farming in recent years by using panel data on 56 organic farms mainly engaged in milk production for the period 2002 to 2004. Based on a translog production frontier framework the technical and scale efficiency on farm level is analyzed by considering also curvature consistency. The total change in productivity for the reference period is measured by using the Malmquist total factor productivity index approach based on a time trends as well as a general index model specification.

    Farmers in peri-urban regions face many problems, among which land scarcity is a major one according to literature. However, as indicated by a survey among farmers in the peri-urban region around Brussels, land scarcity is not perceived as a problem by all farmers to the same extent.

    The main question in this research is to what extent agriculture on fragile slopes would become more sustainable if the farmers were given more possibilities for selling their products and acquiring production resources. An empirical study conducted in northern Benin demonstrates that a more accessible market does not lead to substantial increase in soil erosion control measures.

    This paper presents a methodology for assessing the visual quality of agricultural landscapes through direct and indirect techniques of landscape valuation. The first technique enables us to rank agricultural landscapes on the basis of a survey of public preferences. The latter weighs the contribution of the elements and attributes contained in the picture to its overall scenic beauty via regression analysis. The photos used in the survey included man-made elements, positive and negative, agricultural fields, mainly of cereals and olive trees, and a natural park.

    How can rights of first refusal protect prime agricultural land? This paper develops a theory for valuing rights of first refusal based on compensation for foreclosing future demand, information asymmetry, and advance purchase of market share. A procedure is developed for governments to use these rights to prevent conversion.

    A simultaneously determined model for farm size and government payments along with the incorporation of a recursive impact of government payments and agricultural returns was used to examine farm size changes nationally and regionally. The results clearly demonstrated resource substitution influences, differences in the nonfarm economy, and agricultural returns in explaining farm size.

    The federal grazing fee is currently set using the Public Rangeland Improvement Act (PRIA) fee formula established in 1978 and modified in 1986. The formula is adjusted annually using indices of private land grazing lease rates (Forage Value Index, FVI), prices received for beef cattle (Beef Cattle Price Index, BCPI), and costs of beef production (Prices Paid Index, PPI). The FVI tracks price movement in the private forage market and was the only index originally proposed to be included in the fee formula.

    This paper examines whether better property rights will increase joint productivity of agricultural and timber products in the Brazilian Amazon. Farrell output-based technical efficiency and technological progress measures are derived by using DEA (Data Envelopment Analysis) for Amazonian counties and are regressed on non-discretional variables such as land title. Land title is found to significantly improve the technical efficiency.

    In this paper, a theoretical model is developed to analyze the interactions among residential development, land use regulations, and public financial impacts (public expenditure and property tax). A simultaneous equations system with self-selection and discrete dependent variables is estimated to determine the interactions for counties in the five western states (California, Idaho, Nevada, Oregon, and Washington). The results show that county governments are more likely to impose land use regulations when facing rapid land development, high public expenditure and property tax.

    A binary choice model was used to identify the attributes that influence irrigation district adoption of conservation rate structures. Using principles of rate design and irrigation district administration as a framework, measures of irrigation district rate structure objectives and physical and economic conditions were developed. The factors investigated characterize the constraints under which districts operate, value and cost of water, quantity of water delivered and revenue risk for districts. Rate structure adoption was predicted with over 75% accuracy.
